This paper argues the philosophy of George Berkeley's on "immaterial hypothesis" of reality. George Berkeley's "immaterial hypothesis" states that only what is perceived by the mind exists. Therefore, material objects - those perceivable by the senses - are only ideas and sensations, collected and stored in the mind that perceives them. And because only rational beings have minds, only they (or persons) exist. His first or earliest argument dealt with the relation between objects of sight and objects of touch. He held that a man born blind may have an idea of an object by touching it, and when he becomes able to see, his concept of that object, now that he sees it, may be the same concept as that, which he already knows by touching. If this is the case, it is because what he knows by touch and what he now knows by sight have the same qualities or something in common.
